To take flight, helicopters utilize a combination of specialized components to achieve such capabilities. While most modern helicopters come in a variety of sizes and shapes, the critical apparatuses that comprise the aircraft remain fundamentally the same. To achieve flight, primary components of a helicopter consist of the airframe, fuselage, landing gear, powerplant, transmission, main rotor, and anti-torque system. While all of these parts are needed and contribute to flight, the rotor system in particular is a major section that separates helicopters from other aircraft types. Without these correlating sections of the rotorcraft, flight would be compromised and unsafe for pilots.

The oil system of an aircraft is paramount to its performance, allowing for numerous parts to be lubricated and cooled during standard operations. Over time, oil may be exposed to numerous contaminates that can affect performance, and common contaminants include gasoline, acid, dirt, moisture, carbon, and metallic particles. To prevent these contaminants from having major effects on the lubrication system, the regular draining and replacement of oil should be conducted. In some cases, however, maintaining the oil system may require more than simply replacing liquids as one may need to clean parts, check aircraft oil filters, replace damaged components, and more.

The helicopter rotor system is the rotating section of the aircraft that generates lift. The rotor is made up of the mast, hub, and rotor blades. The mast is a hollow, cylindrical metal shaft that extends up from the transmission. In some configurations, the transmission also supports the mast. Atop the mast lies the attachment point for the rotor blades. This is called the hub. The rotor blades can attach to the hub through a variety of means. In fact, the type of rotor system is determined by the way the blades are attached to the hub. There are three different rotor systems: semirigid, rigid, and fully articulated. This blog will explain each of these rotor systems, as well as the rotor types themselves.

Rivets are an indispensable mechanical fastener for the construction of aircraft assemblies. Rivets feature a cylindrical shaft that has a head on one end and a tail on the other, providing the ability for the rivet to be passed through components before the tail end is made into another head. When the tail is formed into a head, the rivet then acts as a permanent fastener, supporting tension and shear loads without the risk of loosening. While solid rivets have proved their use since the Bronze Age, they always require access to both sides of a component for proper installation and head formation. This can create problems and consume time for aircraft assembly where accessing the other side of a component proves to be very difficult. Luckily, fasteners such as blind and pop rivets solve this problem by allowing installation from one side of the component. In this blog, we will discuss what blind and pop rivet parts are, and how they differ from each other.

Altimeters are a very useful tool for a variety of applications including flying aircraft, hiking, climbing, skiing, and more. Altitude measurement is made by determining atmospheric pressure, otherwise known as barometric pressure. Atmospheric pressure refers to the pressure that is caused by gravity pulling in the air from the atmosphere towards Earth. As pressure is caused by the accumulated air weight, atmospheric pressure is reduced while travelling upwards in elevation. With an understanding of atmospheric pressure and how it differs depending on elevation, we can now discuss how the altimeter aircraft feature provides pilots with altitude readings.

When designing rotor blades for a new helicopter, the length is often decided based on the intended application. With longer helicopter rotor blades, more powerful lift can be achieved which is optimal for carrying heavier loads. Smaller blades on the other hand allow for less drag and faster achievable speeds. With the advent of new technology and capability, the ability to have both types with the same rotor may soon become a reality.

The next time you’re outside, turn your eyes to the sky and you will most likely see a few vapor trails above us. These are the white wispy lines that jet engine planes paint across the great blue sky as they zoom across the horizon. These lines are made by the engines inside the plane that powers them, specifically, jet engine propulsion. This type of engine converts energy rich liquid fuel into a powerful force called thrust. The thrust, in combination with lift, forces air past the wings to power it into the sky and enable flight. Let’s explore how jet engines function and how they vary from piston engines.

One of the most important parts of any rotorcraft is undoubtedly the rotor. But the blades are a close second. Afterall, for rotorcraft, the rotational movement of the blades is the only reason that the aircraft can even achieve lift and fly. For rotorcraft like helicopters, lift is achieved when the rotor blades (airfoil) meet the oncoming airflow and deflect them, creating a change in the direction of the airflow, which results in an area of low pressure forming behind the leading edge of the upper surface of the blade.

The propeller is the one of the most vital parts on your aircraft, and one of the most vulnerable. The aircraft propeller is the main component used to generate thrust, consistently stressing the propeller. The likelihood of the propeller sustaining damage is substantially higher than it is for the rest of the airframe. So, it’s important to care for the propeller and conduct regular visual inspections. Fortunately, proper propeller care doesn’t require a specialized technician, nor will it take a lot of time. By following these few easy steps, you can remain vigilant on your propeller’s condition and remain confident when cruising at 15,000 feet.
